Hi Benjamin,<br>
<br>
To use <b>ECW</b> in <b>server</b>-based products requires
additional licensing permissions.<br>
<br>
If you have the licence agreement, you can build GDAL with ECW, but
you also need to build QGIS Server with ECW support.<br>
<br>
Regards,<br>
René-Luc<br>

student at the University of Lille, I recently gained
access to some mapfiles so I'm not accustomed to qgis yet.
I would like to use a map server to share these files
inside of my local network.</div>

to be as complete as possible so I did some research and I
found some libraries such as kea, Mr.Sid or ecw which can
be built with gdal in order to read different files'
types.</div>

with kea and Mr.Sid which work on my server, however, when
I used ecw with the free version of SDK and I completed
the installation, I got a warning saying that ecw had been
skipped in the server and when I added an ecw file to a
qgis project, my project wasn't working anymore (request
timed-out).</div>

I made a mistake during the installation, ecw has a server
supported version while I used the free desktop version.
Does the skipping issue come from the difference between
licenses?</div>
